摘要： There is provided an electrode material for electricity storage devices, which enables suppression of heat generation in charge and discharge at large currents. The electrode material for electricity storage devices comprises a first carbon material having a graphite structure wherein graphite is partially exfoliated, and a second carbon material different from the first carbon material, wherein the ratio A/B, where A represents a weight of the first carbon material and B represents a weight of the second carbon material, is within the range of 0.01 or higher and 100 or lower.

摘要： Provided is a carbon material that can improve the cycle characteristic in charge and discharge of an all-solid-state battery. The carbon material is a carbon material to be contained in a positive electrode and/or a negative electrode of an all-solid-state battery comprising a group 1- or group 2-ionic conductive solid electrolyte, wherein in an X-ray diffraction spectrum of a mixture of the carbon material and Si in a weight ratio of 1:1, a ratio a/b is 0.2 or higher and 10.0 or lower, where a represents a height of the highest peak in the range of 2θ of 24° or larger and smaller than 28° and b represents a height of the highest peak in the range of 2θ of 28° or larger and smaller than 30°.
